"Anwar and Kendall are just having fun for now," the source said. "Both of them recently got out of relationships, and don't want anything too serious."

"Kendall is best friends with Anwar's sisters, Gigi and Bella, and she respects them tremendously," the source continued. "Kendall would never want to do anything to put her relationship with Anwar's sisters in jeopardy. Kendall and Anwar have known each other for years and have always been flirtatious and this is just another sign of that. The two enjoy one another's company and things could change, but for now, it's nothing serious."

As for Simmons? She's still seeing him, according to the source. You do you, Kendall. You do you.
